What is the difference between a baffled tank and a smooth bore tank?

TANK TYPES: BAFFLED TANKS: Have baffles (bulkheads with holes) inside that slow down the front-to-back movement of liquid, reducing surge; the holes let liquid flow through while breaking up the wave action; BUT baffles do NOT reduce side-to-side surge; SMOOTH BORE TANKS (unbaffled): Have no baffles inside — nothing to slow the liquid; used for FOOD PRODUCTS (milk, juice) because baffles are hard to clean and sanitize (sanitation requirements); smooth bore tanks have the GREATEST surge in all directions; drivers of smooth bore tanks must be extremely cautious with smooth, gradual driving; SIDE-TO-SIDE SURGE: A concern especially when changing lanes, turning, or on curves — can affect stability and contribute to rollover; understanding the tank type helps the driver anticipate how the liquid will behave; smooth bore food tankers require the most careful driving due to maximum surge.
